The main aim of the present study was to examine some psychometric properties of the Psychopathy Checklist: Youth Version (PCL:YV) among Portuguese juvenile delinquents. With forensic sample of 192 incarcerated male participants, the Portuguese version of the PCL:YV demonstrated promising psychometric properties of the three-factor model of youth psychopathy, internal consistency, convergent validity, concurrent validity, and retrospective validity that generally justify its use among Portuguese youths. Statistically significant associations were found with age of criminal onset, frequency of crimes, number of victims, and use of physical violence.

Acoustic signals can encode crucial information about species identity and individual quality. We recorded and compared male courtship drum sounds of the sand goby Pomatoschistus minutus and the painted goby P. pictus and examined if they can function in species recognition within sympatric populations. We also examined which acoustic features are related to male quality and the factors that affect female courtship in the sand goby, to determine whether vocalisations potentially play a role in mate assessment. Drums produced by the painted goby showed significantly higher dominant frequencies, higher sound pulse repetition rates and longer intervals between sounds than those of the sand goby. In the sand goby, male quality was predicted by visual and acoustic courtship signals. Regression analyses showed that sound amplitude was a good predictor of male length, whereas the duration of nest behaviour and active calling rate (i.e. excluding silent periods) were good predictors of male condition factor and fat reserves respectively. In addition, the level of female courtship was predicted by male nest behaviour. The results suggest that the frequency and temporal patterns of sounds can encode species identity, whereas sound amplitude and calling activity reflects male size and fat reserves. Visual courtship duration (nest-related behaviour) also seems relevant to mate choice, since it reflects male condition and is related to female courtship. Our work suggests that acoustic communication can contribute to mate choice in the sand goby group, and invites further study. © 2013 Pedroso et al.

Animals often vocalize during territorial challenges as acoustic signals may indicate motivation and fighting ability and contribute to reduce aggressive escalation. Here, we tested the function of agonistic sounds in territorial defence in the painted goby. Pomatoschistus pictus, a small vocal marine fish that defends nests during the breeding season. We first measured the number of times a male approached, avoided, explored, entered and exited two unattended nests associated with either conspecific agonistic sounds or a control: silence or white noise. Acoustic stimuli were played back when the male approached a nest. In a second experimental set, we added visual stimuli, consisting of a conspecific male in a small confinement aquarium near each nest. Even though we found no effect of the visual stimuli, the sound playbacks induced similar effects in both experimental conditions. In the sound vs. silence treatment, we found that when males approached a nest, the playback of conspecific sounds usually triggered avoidance. However, this behaviour did not last as in longer periods males visited nests associated with agonistic sounds more often than silent ones. When the control was white noise, we found no significant effect of the playback treatment in male behaviour. Although we cannot exclude the possibility that other sounds may dissuade nest occupation, our results suggest that agonistic sounds act as territorial intrusion deterrents but are insufficient to prevent nest intrusion on their own. Further studies are needed to test the significance of sound production rate, spectral content and temporal patterns to deter territorial intrusion in fish. © 2013 Blackwell Verlag GmbH.

Transcriptome data are a good resource to develop microsatellites due to their potential in targeting candidate genes. However, developing microsatellites can be a time-consuming enterprise due to the numerous primer pairs to be tested. Therefore, the use of methodologies that make it efficient to identify polymorphic microsatellites is desirable. Here we used a 62,038 contigs transcriptome assembly, obtained from pyrosequencing a peacock blenny (Salaria pavo) multi-tissue cDNA library, to mine for microsatellites and in silico evaluation of their polymorphism. A total of 4190 microsatellites were identified in 3670 unique unigenes, and from these microsatellites, in silico polymorphism was detected in 733. We selected microsatellites based either on their in silico polymorphism and annotation results or based only on their number of repeats. Using these two approaches, 28 microsatellites were successfully amplified in twenty-six individuals, and all but 2 were found to be polymorphic, being the first genetic markers for this species. Our results showed that the strategy of selection based on number of repeats is more efficient in obtaining polymorphic microsatellites than the strategy of in silico polymorphism (allelic richness was 8.2. ±. 3.85 and 4.56. ±. 2.45 respectively). This study demonstrates that combining the knowledge of number of repeats with other predictors of variability, for example in silico microsatellite polymorphism, improves the rates of polymorphism, yielding microsatellites with higher allelic richness, and decreases the number of monomorphic microsatellites obtained. © 2013 Elsevier B.V.

In this study of extra-clinical psychoanalysis work applied to the study of artistic cul-tural objects, the author tries to show the relevance of applying of the bionian model of the elements in psychoanalysis, particularly the interrelationships between paranoid-schizoid and depressive positions (PS ↔ D) to the artistic creative process, that is, the understanding of modern artistic works as the result of permanent oscillation between different modes of think-ing / feeling, either dispersive or integrative, illustrated with works from various artistic fields: theater (Brecht’s Galileo Galilei), painting (cubism of Picasso), literature (James Joyce’s Ulysses) and modern dance. © 2015, Sociedade de Psicanalise Iracy Doyle.
